Abstract: A networked game and method for entry of a non-winning game ticket in a second opportunity random draw game using a computer device that communicates with the game provider, each game player having a unique identifier and a determined balance of chips for selective use during game play shown on a display and at least one control feature selectively operative by the game player to play to an outcome for obtaining additional chips or not, with additional chips awarded to the player upon registering a non-winning ticket of a random draw game in the second opportunity game.

Abstract: An electronic apparatus can be placed between the money acceptor and the operative components of a gaming or vending machine to award a bonus based on predetermined utilization rates of the machine. The apparatus may incorporate dip switches to permit the number of bonuses to be varied and to change the frequency at which the bonuses are awarded. In gaming machines the bonus can be in the form of additional credits or increased play, while in vending machines the bonus can be in the form of additional credits or the dispensing of bonus product with the product purchased from the machine. Alternatively, the bonus award system can be incorporated into the money acceptor. In vending machines, a sensor may be incorporated to sense the dispensing of product from the vending machine to ascertain the utilization rate of the machine for the awarding of bonuses.

Abstract: An apparatus for mixing vapor and liquid reactants within a column. The apparatus forms a first mixing zone into which a first reactant (e.g. vapor) is homogenized by swirl flow and flows vertically downward. The apparatus further forms a second mixing zone into which a second reactant (e.g., liquid) is homogenized by swirl flow and flows vertically downward. Additional amounts of either the first reactant, the second reactant or both may be added into or ahead of the first mixing zone or the second mixing zone as appropriate. The first reactant is directed radially to collide in crossflow with a thin sheet of the second reactant to provide intense mixing of the first and second reactants. Due to separate mixing zones for the two reactants, the mixing conditions for each can be tailored to best mix each reactant while minimizing pressure drop and minimizing the space and volume requirements for this mixing.

Abstract: A motor home/soldout detection scheme which can sense N motors home and/or soldout, using only a two wire interface to each motor. The two wire interface can also be matrixed by row and column to further expand the interfacing ability. By channeling the home signal from the control board through the soldout switch the detection of soldout can be assured.

Abstract: A money operated control is used to control and operate a selected one of a plurality of electrical units such as washing, drying or gas-dispensing machines. Each such unit includes a unit controller device operable to control the functioning of the unit upon delivery of a start signal to the unit controller device. A central control panel includes a latching relay which when pulsed to its set state energizes a transformer. The transformer in turn energizes a switching unit in the central control panel which selects one of the electrical units to be energized. The actuation of the selected electrical unit resets the latching relay to its original condition and additional relay circuitry is provided so that the connection to the machine in use does not interfere with subsequent operation of the control panel to select other machines.

Abstract: This invention is a coin operated switch which may be incorporated into coin operated machines such as video games to reduce cheating of the credit granting feature of the machines. This invention incorporates two electromechanical switches and circuitry which further use the existing machine circuitry to time the travel of a coin between the switches and to grant a credit on the machine only if each switch is tripped and released in the proper order and within the predetermined elapsed time.
